The surface of Jiao-Je, an EuCytherean world with a surface temperature of 500 K. The refrigerated habitats and craft shown in this image are slowly being replaced by infrastucture designed for high-temperature tweaks.

Major sub-type of Cytherean Type planet. The greenhouse effect is quite pronounced, with temperatures sometimes exceeding 1,000 degrees Fahrenheit. Geological activity varies, depending on planetary mass. Life is absent. indeed, these worlds are perhaps the most inhospitable known, thanks to high temperatures and high surface pressures.
